Sanyo Eneloop Stick Booster KBC-D1BS was announced in Japan back in August 2010 but unfortunately it is not available in Singapore. My mom’s business friend came to visit us on a business trip and I asked him to help me get the Eneloop Stick Booster from Japan. It cost 2980 Yen which is about S$46.30. I like it because of the design.
It is capable of outputting 5.0V/500mA through its output port but unfortunately, you can’t charge your Eneloop batteries in it as there is no input/charging port. It has a rating capacity of 1,900mAH and hence it should be able to full charge your iPhone at least 1 time. For more detail specifications, check out this pdf file.
